Replaced lock button and sensor cable on iPhone 4

Il Mio Problema

Lock button on iPhone 4 didn't work

La Mia Riparazione

The guides worked perfectly! Took me about one hour. The magnetic project mat was great since the parts was small.

Il Mio Consiglio

I didn't have to replace the power button itself - its in metal and was not broken. The problem was the sensor cable where the switch was attached. The phone worked flawlessly after the repair!
